Abstract

Carbamide-formaldehyde oligomer is modified with poly(vinyl acetate) dispersion taking into account the basic notions of the theory of adhesive wetting. It is established that this type of modification makes it possible to enhance the adhesive properties of carbamide-formaldehyde oligomer to the flax boon and to improve the qualitative characteristics of boon boards. The optimal amount of modifier is determined. Results of measuring contact angles and calculating surface tension of modified adhesive compositions are reported.
